Abstract:
A film includes a substrate including a cyclic olefin-based resin; and an easily adhesive layer adjacent to the substrate, in which a content of a fluorine-containing polymer in the easily adhesive layer is greater than 20 mass % with respect to a total mass of the easily adhesive layer. This film is used in a transparent conductive film, and this transparent conductive film is used in a touch panel. A method for producing a film includes laminating an easily adhesive layer by directly applying a coating liquid for forming an easily adhesive layer on a substrate including a cyclic olefin-based resin, in which a content of a fluorine-containing polymer in the coating liquid for forming the easily adhesive layer is greater than 20 mass % with respect to a total mass of the coating liquid for forming the easily adhesive layer.
